# NT8 Strategy Dropdown Complete Fix

## 🎯 Objective

Fix two issues preventing SimpleORBNT8 from appearing in NT8 strategy dropdown:
1. NT8StrategyBase (abstract) incorrectly appears in dropdown
2. SimpleORBNT8 has runtime error preventing it from loading

---

## 🔧 Fix 1: NT8StrategyBase.cs - Remove Name from abstract class

### File
`src/NT8.Adapters/Strategies/NT8StrategyBase.cs`

### Problem
Abstract base class sets `Name = "NT8 SDK Strategy Base"` which makes it
appear in the strategy dropdown. Abstract strategies should NOT have a Name.

### Change: Remove or comment out Name assignment

**Find (around line 97):**
```csharp
        protected override void OnStateChange()
        {
            if (State == State.SetDefaults)
            {
                Description = "SDK-integrated strategy base";
                Name = "NT8 SDK Strategy Base";
                Calculate = Calculate.OnBarClose;
```

**Replace with:**
```csharp
        protected override void OnStateChange()
        {
            if (State == State.SetDefaults)
            {
                Description = "SDK-integrated strategy base";
                // Name intentionally not set - this is an abstract base class
                Calculate = Calculate.OnBarClose;
```

## 🔧 Fix 2: SimpleORBNT8.cs - Guard Instrument null access

### File
`src/NT8.Adapters/Strategies/SimpleORBNT8.cs`

### Problem
`ConfigureStrategyParameters()` accesses `Instrument.MasterInstrument` which is
null when NT8 loads the strategy for the dropdown list, causing a runtime
exception that removes it from available strategies.

### Change: Add null guard

**Find:**
```csharp
        protected override void ConfigureStrategyParameters()
        {
            _strategyConfig.RiskSettings.DailyLossLimit = DailyLossLimit;
            _strategyConfig.RiskSettings.MaxTradeRisk = MaxTradeRisk;
            _strategyConfig.RiskSettings.MaxOpenPositions = MaxOpenPositions;

            var pointValue = Instrument.MasterInstrument.PointValue;
            var tickSize = Instrument.MasterInstrument.TickSize;
            var dollarRisk = StopTicks * tickSize * pointValue;

            if (dollarRisk > _strategyConfig.RiskSettings.MaxTradeRisk)
                _strategyConfig.RiskSettings.MaxTradeRisk = dollarRisk;

            _strategyConfig.SizingSettings.RiskPerTrade = RiskPerTrade;
```

**Replace with:**
```csharp
        protected override void ConfigureStrategyParameters()
        {
            _strategyConfig.RiskSettings.DailyLossLimit = DailyLossLimit;
            _strategyConfig.RiskSettings.MaxTradeRisk = MaxTradeRisk;
            _strategyConfig.RiskSettings.MaxOpenPositions = MaxOpenPositions;

            // Guard: Instrument is null during strategy list loading
            if (Instrument != null && Instrument.MasterInstrument != null)
            {
                var pointValue = Instrument.MasterInstrument.PointValue;
                var tickSize = Instrument.MasterInstrument.TickSize;
                var dollarRisk = StopTicks * tickSize * pointValue;

                if (dollarRisk > _strategyConfig.RiskSettings.MaxTradeRisk)
                    _strategyConfig.RiskSettings.MaxTradeRisk = dollarRisk;
            }

            _strategyConfig.SizingSettings.RiskPerTrade = RiskPerTrade;
```

## ✅ Verification

```bash
# Build must succeed
dotnet build src\NT8.Adapters\NT8.Adapters.csproj --configuration Release

# Redeploy
.\deployment\Deploy-To-NT8.ps1
```

**In NT8 after recompile:**
- [ ] "NT8 SDK Strategy Base" NO LONGER appears in dropdown
- [ ] "Simple ORB NT8" DOES appear in dropdown
- [ ] "Minimal Test" still appears (if compiled)

---

## 🚨 Constraints

- Two surgical edits only
- C# 5.0 syntax
- Do NOT change other logic
- All tests must pass

---

## 📋 Git Commit

```bash
git add src/NT8.Adapters/Strategies/NT8StrategyBase.cs
git add src/NT8.Adapters/Strategies/SimpleORBNT8.cs
git commit -m "fix: Make abstract base invisible, guard Instrument access

- Remove Name from NT8StrategyBase (abstract shouldn't appear in dropdown)
- Add null guard for Instrument access in ConfigureStrategyParameters
- Prevents runtime error when NT8 loads strategy list

Fixes: SimpleORBNT8 now appears in strategy dropdown"
```
